I tried watching a lot of shows at the same time once and I just couldn't watch any of them properly because they had varied and even total opposite tones and moods, the feeling was similar to tonal whiplash, except between series instead of in-series. Besides it's way harder to focus on the events of a show when you have to keep track of what is happening in other 10 shows.
On another topic, I remember you praising Romance of the Three Kingdoms a couple of times so I'm curious. Did you read the original novel, a summary or one of its adaptations and which one do you recommend?
